      Crashworthiness is a relevant engineering property for car parts. However it is not easy to measure at laboratory scale and complex impact tests have to be carried out to determine it. Crash re-sistance for high strength ...
    • Determination of the essential work of fracture at high strain rates 

      Frómeta Gutiérrez, David; Casellas Padró, Daniel; Jonsén, Par (2017)
      Conference report
      Open Access
      During the last decades, the use of ultra-high strength steel (UHSS) has increased as its favorable ratio between strength and mass allows the design of lighter body-in-white while maintaining passenger safety. Modeling ...
    • Fracture mechanics based modelling of failure in advanced high strength steels 

      Jonsén, Par; Frómeta Gutiérrez, David; Casellas Padró, Daniel (2017)
      Conference report
      Open Access
      In the last decade, the favorable properties of the press hardening process for advanced high strength steel (AHSS) have increased the demands concerning passenger safety and lightweight design. AHSS show excellent mechanical ...
